is a reference document to be used for defining cases, defining variables, entering data, and checking data once they are entered. It contains information about all data elements (i.e., variables) and the way the data are structured. It should be kept on hand when doing data entry, data abstraction, or data checking/reabstraction, both in the office and in the field. It is also a useful guide to understand the way in which NVDRS variables are defined when conducting data analysis. 1.1 Companion documents Starting in 2018, historical information on variables contained in the NVDRS system has been added to a data dictionary, and a description of how key data elements can be used in analyses has been added to the NVDRS Analytic Manual. 1.2 Background on NVDRS Public health leaders and others aware of the long-standing gap in information about violence emphasized the need for a national surveillance system for violent deaths since 1989. In 1999, the Institute of Medicine, currently known as the National Academy of Medicine, recommended that the Centers for Disease Control and Prevention (CDC) develop a fatal intentional injury surveillance system modeled after the National Highway Traffic Safety Administration’s Fatality Analysis Reporting System. That same year, six private foundations pooled their funds to demonstrate the importance and feasibility of data collection about violent deaths given adequate funding. They supported the National Violent Injury Statistics System (NVISS). NVISS was administered by the Harvard Injury Control Research Center and included 12 participating universities, health departments, and medical centers. In 2000, dozens of medical associations, suicide prevention groups, child protection advocates, and family violence prevention organizations joined a coalition whose purpose was to secure federal funding to extend NVISS-like surveillance nationwide. Congress approved $1.5 million to start the new system, called the National Violent Death Reporting System (NVDRS), in fiscal year 2002. The first cooperative agreements were established with six state health departments in September 2002, including: Maryland, Massachusetts, New Jersey, Oregon, South Carolina, and Virginia. Deaths occurring in 2003 constitute the first year of data collection for NVDRS. Funding for additional states was made available in fiscal year 2003 and another seven states implemented NVDRS (Alaska, Colorado, Georgia, North Carolina, Oklahoma, Rhode Island, and Wisconsin). Further funding became available in 2004, and Kentucky, New Mexico, Utah, and four counties in California began data collection in 2005. California ended data collection for these counties in 2009. Also, in 2009 the system expanded, with two more states (Michigan and Ohio) joining NVDRS and collecting data beginning in 2010. In 2014, 14 more states joined NVDRS (Arizona, Connecticut, Hawaii, Iowa, Illinois, Indiana, Kansas, Maine, Minnesota, New Hampshire, New York, Pennsylvania, Vermont, and Washington) and began collecting data in 2015. NVDRS expanded again in 2016 with an additional eight states (Alabama, California, Delaware, Louisiana, Missouri, Nebraska, Nevada, and West Virginia), the District of Columbia, and Puerto Rico joining the system and beginning data collection in 2017. Finally, in 2018, ten states (Arkansas, Florida, Idaho, Mississippi, Montana, North Dakota, South Dakota, Tennessee, Texas, and Wyoming) joined the system and began collecting data in 2019. Starting with the 2019 data year, NVDRS became a national system with all 50 states, the District of Columbia, and Puerto Rico
